Late Night Video: Neil Patrick Harris and James Corden have epic Broadway riff-off

This is all kinds of delicious fun. Neil Patrick Harris dropped by The Late Late Show today to have a Broadway riff-off with host James Corden. These two charming and talented guys launch into a Broadway riff-off that has them trying to outdo each other by belting out parts of songs. NPH does a little bit of Being Alive from Company and Sugar Daddy from Hedwig and the Angry Inch. Corden counters with All that Jazz from Chicago, among others. Enjoy!
